However, in all of the above-mentioned conventional ones, in order to engage and integrate the decorative member with the mounting member, both members must be processed so as to form an engaging structure such as an engaging portion. If the shape or shape is different, there is a problem that it is necessary to arrange the mounting members and the decorative members in that number. In addition, it is necessary to consider the support for cloth finishing as the interior wall surface of the room.

The present invention has been made in view of these points, and an object of the present invention is to improve the structure of a corner member to eliminate the need for complicated processing on the corner member, and to minimize the difference in dimensions and shape. The purpose is to make it possible to handle with a number of members and also to handle cross finishing.

In order to achieve the above object, in the present invention, the decorative member is integrally fixed to the mounting member with an adhesive.

Specifically, the first invention is a corner member installed at an outside corner or an inside corner of an interior wall surface of a building, wherein the elongated flat plate member has an acute angle in the middle portion in the width direction. A mounting member having a cross-sectional shape bent at a right angle or an acute angle, and a decorative member made of a material different from the mounting member and integrally fixed to the outer or inner surface of the mounting member with at least an adhesive, are provided. Protruding portions protruding from the decorative member are formed at both ends of the member, and flat surfaces inclined so as to intersect the protruding portions of the mounting member at an acute angle are formed at both ends in the width direction of the decorative member. A groove-like space having a shape that narrows toward the back side is formed between the flat surface portion and the protruding portion of the mounting member .

In the first invention, the corner member includes a mounting member and a decorative member, and protrusions protruding from the decorative member are formed at both ends of the mounting member. When fastening with nails or the like, the corner member may be fastened with this protruding portion, and staples, screws, nails, etc. do not appear on the surface of the decorative member, and the design is excellent.

Further, since the mounting member and the decorative member are integrally fixed to each other by at least an adhesive, there is no need for an engaging structure for integrating the two members by engagement and a complicated processing corresponding to the engaging structure, and both members can be used. Simple shapes and structures will suffice. As a result, even if the dimensions and shapes of the corner members are different, the minimum number of members can be used.

Further, when the cloth finish is performed on the indoor wall surface next to the corner member, it is only necessary to attach the cloth on the protrusions at both ends of the mounting member, and the cloth finish can be easily performed.

Further, the protruding portion of the mounting member and the flat surface portion located at both ends in the width direction of the decorative member and inclined so as to intersect the protruding portion of the mounting member at an acute angle have a shape that narrows toward the back side. Since the groove-shaped space is formed, the end portion of the wall panel or wall cloth can be inserted into the groove-shaped space having this shape, so that the end portion can be concealed so as not to be seen from the front.

The second invention is characterized in that, in the first invention, the mounting member is made of resin. In this way, for example, when the corner member is fastened to the wall base material, the resin mounting member can be easily fastened not only with nails and screws but also with staples. Further, when the mounting member is fixed to the decorative member with an adhesive, staples, screws, nails and the like can be used together, and the fixing is facilitated.

The third invention is characterized in that, in the first or second invention, a plurality of through holes are formed in the mounting member.

Therefore, the putty processing can be easily performed. Further, if a through hole is formed in the area where the decorative member is adhered in the mounting member, the through hole is filled with an adhesive to obtain a kind of anchor effect, and the adhesive strength between the mounting member and the decorative member is obtained. Increases.

The fourth invention is characterized in that, in any one of the first to third inventions, the decorative member is made of a volcanic vitreous multilayer plate.

In the fourth invention, since the volcanic vitreous multilayer plate is used as the decorative member, the decorative member is an inorganic material and has non-combustible performance. Further, even if the decorative member is added to the mounting member with an adhesive and staples or the like are used in combination, the material can be fastened without cracking.

In the fifth invention, any one of the corner members of the first to fourth inventions is installed on the protruding corner or the inside corner of the interior wall surface of the building, and the interior wall surface excluding the outside corner or the inside corner is covered. In a cloth finishing construction structure to which a cloth is attached, the corner member is fixed to the protruding corner or the inside corner by a mounting member, and another wall surface adjacent to the protruding portion from the protruding portion of the mounting member. The putty is applied over the cloth to form a cloth base surface, and the cloth is attached on the cloth base surface.

In the sixth invention, any one of the corner members of the first to fourth inventions is installed on the outer corner or the inner corner of the interior wall surface of the building, and the cross is applied to the wall surface excluding the outer corner or the inner corner. Is a cross-finishing construction method in which the above-mentioned corner member is fixed to the above-mentioned protruding corner or inside corner by a mounting member, and the protrusion portion of the mounting member extends to another wall surface adjacent to the protruding portion. The feature is that after the putty is applied to form the cloth base surface, the cloth is pasted on the cloth base surface.

In the fifth and sixth inventions, when the interior wall surface of the building is cross-finished, the corner members are fixed to the protruding corners or the inside corners of the wall surface by the protruding portions at both ends of the mounting member. In this state, the putty is applied from the protruding portion to the other wall surface adjacent to the protruding portion to form a cloth base surface. After that, the cloth is pasted on the cloth base surface. In this way, the cloth finish can be easily performed.

As described above, according to the present invention, a decorative member made of a material different from the mounting member is integrally formed on the outer surface or the inner surface of the mounting member having a cross-sectional shape in which an elongated flat plate material is bent at an intermediate portion in the width direction by an adhesive. It is fixed, projecting portions protruding from the decorative member are formed at both ends of the mounting member, and flat surfaces inclined so as to intersect the protruding portions of the mounting member at sharp angles are formed at both ends in the width direction of the decorative member. By providing a groove-like space having a shape that narrows toward the back side between the flat surface portion and the protruding portion of the mounting member , the corner member is fastened to the wall base material with staples, screws, nails, etc. Occasionally, it can be fastened with a protruding portion to prevent staples, screws, nails, etc. from appearing on the surface of the decorative member, and excellent designability can be obtained. In addition, the integral fixing of the mounting member and the decorative member with an adhesive eliminates the need for an engaging structure for integrating the two members by engagement and the corresponding complicated processing, and the dimensions and shapes of the corner members are different. Can be handled with the minimum number of members. Further, when the wall surface is cross-finished, it is only necessary to attach the cloth on the protruding portion of the mounting member, and the cross-finishing can be easily performed. Further, since the protruding portion of the mounting member and the inclined flat surface portions at both ends in the width direction of the decorative member form a groove-shaped space having a shape narrowing toward the back side, the groove-shaped space having this shape is formed. The edges of wall panels and wall cloths can be concealed.
